IPS Beetles, sometimes known as engraver beetles are bark beetles that develop under the bark of spruce and pine trees. Creating tunnels that girdle and damage the vascular system of your trees, contributing to dieback and eventual death of your tree. Continued periods of draught and other stressors contribute to the proliferation of attacks and infestations.
At HLS Colorado, we recommend a 2x preventative spray program for high value trees at lower elevations-spring and mid-to-late summer.
And a 1x application at higher elevations-early summer
